Field CollectingKeweenaw Peninsula Collecting Trip
20th Aug 2018 21:23 UTCRobert Darabos
I have been through the Marquette Iron Range before, but never to copper country.
Best places to find large amounts of copper?
Places I was thinking of visiting are the Arcadian Mine Dump, Quincy Mine, Mohawk Mine, Wolverine Mine, Central Mine Dump, and maybe Copper Falls Mine.
I don't really care to drive further North than the Kearsage area, unless it would be greatly worth it.
Are these mine dumps legal to collect from? One article I read on the internet stated that you need permission for the central mine... is this still true?

Best places to find large amounts of copper? Probably a rock shop! Most of the piles up there are very well picked over so finding large amounts is nearly impossible. If one is patient however, you can still find great specimens on the piles with some digging and observation, just not car loads.
One thing to note is that, technically, every pile on the Keweenaw is owned by someone, whether that be a person, business, or the county. Most of the county owned and "backwoods" piles you can access with no issues, but the privately owned ones can be more difficult, if not impossible, to gain access. Out of the ones you listed, I can tell you that a) Arcadian is pretty much gone, b) Quincy is off limits, c) some of the Mohawk piles are accessible (the ones north of town). d) Wolverine No. 4 is accessible as far as I know, e) Central is tricky. I have heard it is private, yet I see numerous folks in there especially after 5pm., f) Copper Falls is accessible, but unless you have a 4x4 or plan to walk, they are not easy to reach. Based upon your criteria, Mohawk, Central, and Copper Falls would be off your list as they are north of Kearsarge. However, they are other sites not mentioned that, with a little patience, can produce some fantastic specimens. Of course, stay off any pile posted as "No Trespassing".
In addition, don't overlook the other minerals that can be found on the Keweenaw, and also don't forget about the micro/thumbnail-sized specimens as most collectors seem to pass by these in favour of larger sized specimens, for whatever reason......
Good luck!!!

Wolverine #2 is a spot for copper agates and to a lesser extent solid copper.
Only the Mohawk #3 and #4 are accessible for collecting. All others are privately owned and no collecting permitted. The Cliff, Central, and Wolverine #2 are county owned piles. If any activity is present, please stay away as it would interfere with work.
If you need more information, please drop me a personal message.

The Manganese Mine near Copper Harbor is the type locality for Mcfallite, and it is easy to find. (or was a year ago).

When I was at Tech I always considered the museum the most under-rated place to study on campus, as it had a nice quiet area in which to sit -- which was almost always empty -- and any time you needed a break you could get up, walk around, and check out great rocks. That was when it was on the 5th floor of the EEERC; the museum is now a bit farther away from the main campus, but still one of the best places to visit in the UP.
Perhaps not exactly what Robert's asking about, but absolutely a must-see for anyone visiting the Keweenaw and interested in minerals.
Cheers,
D.

Thanks for the referral. You may want to suggest that on that page write Keweenaw in the key words box and click search.

Copper is of course the biggest interest, but any Manganese minerals, Ankerite, Quartz, Chalcosite, anything awesome for micro mounts (like the basalt at St. Louis Mine), etc would be fine. I'm assuming people look for these much less than the copper.

I corrected the coordinates to the center of the pile. You can now clearly see the State Police Post in the satellite photo.

Day 1: Marquette area -
a.) Sugarloaf Mountain (Epidote)
b.)Presque Isle Park (Clinoenstatite, Agates, Peridotite) (is it legal to collect here?!)
c.) Beacon Hill/Champion Mine (Specularite)
d.) Dickinson County (Goethite, Magnatite, etc - I have no great idea for this place yet)
e.) Black River Pegmatite (or is this picked over and gone?)
Day 2: Keweenaw Peninsula
a.) Painesdale area - Champion Mine and Baltic Mine
b.) Arcadian Mine (ankerite, prehnite, epidote, etc)
c.) Laurium Mine and St. Louis Mine
Does this look like good mines to hit up? Should some be skipped (because they are not allowed for collecting or because they are no longer there). Thanks again!

I know that the area there has few, if any, agates along its shore, since you will be in the Marquette Iron Range region geographically, and not the area of the basalt flows which produced the agates in the Keweenaw.

I might cut a couple back. A couple of them (especially in the Marquette area) I've been to before so I'm just stocking back up.
Do you know any good Manganese-mineral mines near Marquette or Dickinson county?

The Taylor mine in Alberta has nice pyrolusite, manganite, and rhodochrosite + neotocite in one of the test pits. www.mindat.org/loc-3838.html
The South Jackson pit in Negaunee has good manganite, pyrolusite, psilomelane, etc. But it's gated, and on private property. Best to tag along with the Ishpeming Rock and Mineral Club for access.
One the easiest mines to access with Mn minerals is the "Manganese Mine," (not to be confused with the Manganese Mine in the Keweenaw) and its dumps are scattered about the clear-cutting of the power line path. Geothite, pyrolusite, manganite, and if you're lucky, baryte, can be found there. www.mindat.org/loc-125094.html

I've extended the trip to four days, so that should help a lot.
Day 1 and Day 2: Marquette area - Presque Isle, Beacon Hill, Humboldt County Manganese Mine (plus whatever catches my eye)
Day 3: Black River Pegmatite on my way to Crystal Falls to visit Bristol Mine (can I even collect here, btw?!)
Day 4: trip to copper area, mainly for Laurium and St. Louis. Maybe a fast drop through Arcadium or Franklin if I have a few minutes to spare.
Day 5: probably a lot of pain killers and sleep :)
